Re: Sometimes, nobody inside cares what *you* think
How is "localhost" ALWAYS turned into 127.0.0.1 ?? By calling the, errr, resolver library. Which will obey whatever rules are in its configuration to turn the string "localhost" into an IPv4 or IPv6 address.
This is known as resolving.
Or did I miss something ironic in your comment ?
Re: What's to look forward to?
A Gb switch is still a Gb switch
Compare what's on the PCB of a current Gb switch with one manufactured 10 years ago. That will give the lie to your assertion that "There is no active development....". Of course, the goal of all that development was driving the manufacturing cost down (you know, commoditisation) rather than putting (mostly) all sorts of nice new shiny in so that Marketing can claim all sorts of new functionality.
Really, the software business model is completely out of kilter with every other product category in the industrialised world, and badly needs some serious disruption. The cloudy rental model isn't it. And I don't believe the problem is technological (software development models and all that)
Re: I knew that had got expensive... but not THAT expensive!
Can't say I'm surprised.
There's a trail of companies that used to be in components and either walked or died. Mostly the latter.
Oh yes, remember that.
They should have patented that business model and then gone after Monster.
Re: I knew that had got expensive... but not THAT expensive!
Upvote for your CPC recommendation.
Though their big catalogue is, well, BIGGGGGG. Received one at work and at home.
Re: But ...
I would have shared your pessimism.
But I suspect commercial, as well as technical, reality will endure this just doesn't happen.
After all, DAB has been such a success, hasn't it ?? And all new cars come with DAB radios that perform just fine, don't they, just like we were promised ??
Agreed, though it could be argued that the first will help bring about the rest.
Not convinced, myself, but as I say, it could be argued.
Where to begin with just how crass and over-simplified this is ??
One other commentard has mentioned ITSO. Let's not forget that it's been 15+ years in the gestation. Roll it out on a grand scale now and the tech will have a few years rather than a couple of decades of life - not a good idea. As far as I can tell the delays have all been around the politics of its introduction rather than anything conceptual or technical. So maybe the goal of this outfit should be how transport operator contracts and regulations should be recast rather than anything else. Still that would be too much like addressing the root of the problem, wouldn't it ???
Look at Oyster - it took a combination of a loaded gun to the head and bribery to get the Train Operating Companies to accept it. Notwithstanding that, the stupid Oyster Extension Permit (OEP) for Oyster season ticket holders using PAYG balances to travel out-of-zone remained a non-negotiable for them. The implementation costs of that were wasted as the TOCs realised within a matter of weeks of rollout what everyone else was telling them - it did nothing to manage fare evasion and was as user-friendly as a cornered cat.
If TfL do manage to get a workable solution (including daily capping) using payment cards, just what will this bring to the table ??
Bizarre. Anyone would think there was an election round the corner. Oh, hang on.
And how does an atom 'flip'?
As you're clearly too lazy to use Google, I used it for you. The search term "cesium clock operation" seemed like a good one. The link to How Stuff works sort of explained it but in a woolly way, but a snippet from here explains the physics very succinctly:
"The atoms in pure cesium exist mostly in two slightly different forms: A low energy form and one with just a bit more energy. For an atomic clock these two states have two properties critical to making a clock. One, they can be separated by a magnet. And two, the lower energy atoms can be converted to the higher energy ones if we bombard cesium with the right radiation."
The process of converting to a higher energy is what's referred to as "flipping" And it's the frequency of this "right" radiation that determines a second. HTH, HAND, and all that jazz.
Re: Every sysadmin must make one really big screw-up in their career
Then there was the trainer (not me !!) at ... well, better not mention where....
He managed to delete all of /etc
Not just once
Not even twice
But three times (over a matter of weeks).
It was a long re-install (from floppies) on a 3B2. Oops, gave it away.
Some years later, I myself did manage to blow away /etc by mis-typing vi as ci. ci didn't check the inode type before doing its work. That hurt.
Thanks for the heads-up. Shame it ends on Saturday, then, and I don't have a free evening before then
With its use of ... (a) partially borrowed script and threadbare plot, Privacy is more of a show than a play. But it’s a decent show.
If that's your premise, I'd wholly disagree.
Is it the show's intention to make us think, challenge our preconceptions, change our behaviours ?? If so, then a show won't do it. It needs to be theatre - proper theatre. I've done no stage stuff since my school years, but my son went from the Brit shcool to MMU Crewe's CTP course. I understand from him a little of how theatre should work, and always remember his utter disdain for the show of the Hutton Inquiry, where the thing was read out verbatim. This neither challenged the audience nor added anything to the corpus of knowledge - and from this description, it seems Privacy is much the same.
Still, maybe I should go see it just in case....
Re: memory- @Tom 7
C shell ?? Pah. That had history and in-line editing.
Real sysadmins used the Bourne Shell (mostly coz I started off on AT&T System III and we didn't have the C shell...)
Someone fell for the autocorrect
.....and Linux mainstay systems, which helps developers command a cluster of CoreOS machines.....
You meant systemd there, not systems.
I will not ignite a flameware here about the design of systemd......
...Google presumably also benefit from being able to say that *they* aren't making any editorial decisions about what gets published on their site
No. Google benefits from the massive advertising revenue they collect on aggregate from their services. Everything they do is predicated on maximising that, directly or indirectly. Period. Always bear that in mind when looking at their motivations.
NNDR does go to central government, but is then re-distributed back to local authorities as an element of the grant.
This is the reason that a 1% change in council spending translates to a 3% change in your council tax. Until this changes, there's no way that local authorities can be transparent or realistically accountable to their local electorate. As it is, they really are little more than an arm of central government. Whatever Eric Pickles might claim. And don't get me started on the proportion of our council tax that goes into the unsustainable local government pension scheme.
I speak as one who, back in the day, was told off like a naughty schoolboy by a minister for breaching their limit on council tax rise by <0.1%.
Re: Clouds are so last week
You should be cynical about the IoT. In particular, the security capabilities of the average device.
Re: Active X is the root of all evil
They really ought to be sued for not taking Active X out back and replacing it with a proper sandbox system.
No. They really ought to sued for ignoring everyone with the slightest bit of ITSEC understanding who told them long and loud that ActiveX Was A Really Bad Idea. Their feeble, pathetic response was "it's what our users want". I don't think their users really wanted their machines pwned. Perhaps they asked their users the wrong question.
The history of ActiveX ever since it escaped has been trying to fix all the holes that everyone told them it would have.
Re: This sort of thing doesn't happen
This is the future of computing - machines that spend 100% of their processing power on security algorithms and that do zero actual work. Correct that - this may actually be the current state of computing.
It most definitely is the current state of computing. I well remember Intel suggesting that the advantage of a second core (when the first dual-core CPUs came out) was that it could run the AV software while the first core did real work (since of course no software was multi-threaded back then)
"There is an ofcom guideline NICC ND1016 which states that a callerid which is set by the carrier should be correct so that a call made back to that number should reach the original caller."
Which is of course honoured far more in the breach than the observance.
You ever tried calling back a silent direct marketing call ?? Or one of those with a UK number that are clearly coming from a sweatshop call centre in Mumbai/Durban/etc ?
Re: CLI freely spoofable on ISDN
Whereas that wasn't the case for me. Did you test more than one ISDN circuit ?? If not, it might have been misconfigured at the exchange (By BT ?? Shurely not !!)
Re: The problem isn't Copyright, it's the corporations.
@rm -rf /
Where to begin ?? Probably with your attempt at a parallel with pubs. As ever, their demise is not down to a single factor, but that unfortunate nexus of a number of things taking place. I'd argue that the legislation to end tied houses was (what a surprise) poorly thought out and drafted, and led to Punch and the other companies setting themselves up as highly-geared property companies. Add to this the value of the sites either as housing or local Tescos/Sainsburys and then, even before we get to the changes in drinking/socialising habits, it gets hard for a pub to be profitable.
So... on to whether copyright is useless ?? Absolutely not. Without copyright law, then Creative Commons licenses wouldn't exist. The ability for someone creative to have a range of choices as to how their creation is used, with or without payment, is crucial to protecting that creativity. The removal of the middle man is the great effect of mass electronic communication, and has hardly begun to play out.
The artists I've discovered through the internet have led to me finding out about gigs I'd never have known about - and paid for - otherwise.
@ChrisMiller - The IBM I/O channel was so well-specified that it was pretty much a standard. Look at what the Systems Concepts guys did - a Dec10 I/O and memory bus to IBM channel converter. Had one of those in the Imperial HENP group so we could use IBM 6250bpi drives as DEC were late to market with them. And the DEC 1600 bpi drives were horribly unreliable. The IBM drives were awesome. It was always amusing explaining to IBM techs why they couldn't run online diags. On the rare occasions when they needed fixing.
Re: So does OSX and Linux...
He's used Ubuntu for years but had swapped it for MacOS because the updates continually broke stuff
That's the price you pay for using a distro that "is never more than six months away from the latest version of anything in the open-source world." (http://www.ubuntu.com/about/about-ubuntu/ubuntu-and-debian). It's too bleeding-edge for stability - if you want that, use RedHat/Centos or Debian.
Horses for courses, old chap.
Re: XP will only be insecure if connected
I have a "customer" (in the sense that it's the precision engineering firm that my wife's ex used to own/run and I help them out occasionally) who has an NC machine tool controlled by a PC.
It runs Windows 95. The hardware includes a Hercules graphics card and one of those multi-serial boards. The issue isn't the software - coz of course it will never, ever see the internet or a USB device and It Just Runs (tm). The worry is the hardware. Three years ago I sourced a populated motherboard, a herc graphics card and a hard disk that are pretty much identical to the system, and cloned the software it onto the hard drive. I doubt I could obtain them now. The only worry is that multi-serial card. I have no idea if/when they'll replace that machine tool. All I know is it meets their needs today, which are of course driven by their customers.
Re: This makes no sense
Maybe it's my Unix background, but I know that if i tell the system to delete something, the inode's listing will be removed from the directory I deleted from, But if the inode is listed in another directory somewhere else, the data will still be on the disk. And if the inode is open in a running process, the data will remain on the disk until the process exits or otherwise closes the inode.
I'd have thought that the reason there are so few people on the job market who've gone through the pain of going from 500 servers to 10000+ is:
a) There aren't that many organisations who've done it.
b) For those who have done it, they recognise that keeping the skilled people who did it (and gained said skills through doing it) is crucial to their ongoing business success. So everything is done to keep them sweet.
Until, of course, the organisation changes ownership, at which point all bets are off.
Re: Oh the security....
The Due Diligence issues can be summarised in one word
All the while an administrator (financial, that is, not systems) can say "Pay us more than you agreed to contractually or we won't return access to your data to you", just what cost/reliability improvements are really there vs rolling your own, if you properly risk-manage this ELE possibility ??
He cannot be serious. Oh, he is....
Dave Coplin, chief envisioning officer at Microsoft [.....] agreed the "main challenge is the human element" as big data forces a change to scientific approach - moving from trying to work out why something happens to a "world of correlation based on sample sizes".
Errr, WTF ?? Yes, statistical correlation based on sample size is useful to validate theories (cf Higgs Boson, etc) - but that's based on a prediction of what should be observed if a theory about "why" is correct.
You don't, and can't, work the other way round. You may get a clue from correlation as to the "why", but that's just a pointer for further research and then working out a further set of predictions that you then validate experimentally.
For the result of applying correlation directly to causation, just look at all the crappy public health policies we've had over the last couple of decades, some of which are at last unravelling.
No wonder HP found Autonomy wasn't worth as much as they thought.
nah, I learnt Algol 68 on an ICL1902 (I think it was) at Kingston Poly in the summer of '72, between Lower VI and Middle VI.
Mind you, our Head of Maths had been offered a redundant IBM M/F but we didn't have the space. Or big enough incoming mains. That would have been fun.
I've used Microsoft Exchange a few times over the years, but it is a pain to configure and still needs a lot of work.
The latest complaint from my users is that as soon as they change a new appointment to "all-day", it automagically changes the status from "busy" to "free". Which leads to appointments being put into peoples' holidays, unless they notice this and change it back again. Needless to say, googling reveals lots of moans about this and the inevitable "fix" that "fixes" an entirely different issue, nevertheless being flagged as the "answer" by some Microsoft forum moderator.
"The first person to create a Linux-on-ARM compatible drop-in Exchange replacement will become a very rich person indeed. But to the best of my knowledge it hasnt happened yet."
I see arm in the available architecture list....
Not, of course, that a few people will become rich on the back of this. But plenty will make a decent living, which is acceptable to me.
Re: A timely reminder to all
The most recent timely reminder (before this one) was that O2 wholesale outage in Northamptonshire (and surrounding areas) when it turned out that Level 3 had a PoP in a light industrial unit, when an adjacent unit caught fire. So much for VESDA and automated fire extinguishing systems...
Re: The real biggest holdup
How I wish I could upvote that 100 times. Closed hardware is the biggest barrier to Android updates and alternative "ROM"s - look at devices like the Galaxy Y S5360 with the Broadcom BCM21553 chipset - which doesn't have an updated BLOB so no chance of Cyangenmod running on it - even if it did have enough memory.
Give them credit. It's quite an achievement to find a courier worse than ShittyLink, wot they always used to use.
Re: 'thought leadership'?
Yeah, Dr. Peter Cochrane OBE suffered the same fate. If he'd been listened to, we'd have FTTP and picocells nationally by now.
But, as ever, the visionaries were ignored.
Re: Good Riddens
You're talking about data over powerline devices within a property. This article is about data over telephone wires into the house - the delivery of internet services into a property.
Some similarities, but also some huge differences in the issues. For instance, modern "outside plant" is built with twisted pair wiring that has a reasonable degree of transmission-line characteristic at (low) radio frequencies. Mains cabling within a property has no such characteristic.
Re: Not a problem for DSL
Tell that to everyone who's broadband goes TU once the house next door gets covered with christmas lights and their dodgy controllers..... I guess I should have been a bit more generic about what I meant by "high-powered transmitter".
It works both ways, too - not only does the RF electrical signal leak out as electromagnetic waves thanks to the (very) imperfect transmission-line qualities of the local loop, but for the same reason the data signal is susceptible to high field-strength radio signals. There is clever defence against impulse noise (the most common universal source) but a high-power transmitter in your vicinity could well play havoc with the xDSL signals.
Re: Learning from mistakes
"That's the design of DNS - single master - not much Microsoft can do about that...."
Errr, no. How the database is setup is entirely separate from the client view of the domain. Single-master is the original design of the most-commonly used DNS server - ISC BIND - which is where you may have got that idea.
To give them a little credit, the MS DNS server gets its data from AD, so the data is mirrored at each AD/DNS server. However, its tight integration with AD makes the validity of the AD structure a single point of failure, and reduces the speed at which rollback can take place. As shown by this outage, it would seem. It's also a bit of a security risk to run DNS and AD on the same server, but I presume MS have separate caching servers facing the outside world to manage that risk (Ahem....).
Powerdns can use a range of backend databases, and using, for instance, PostgreSQL, can have a multi-master backend, with sub-minute rollback if set-up right.
Re: "You really are becoming the replacement Eadon"
"All the IP stack stuff is in the registry"
Whaaaat ??? Since when did executable code live in the registry ??
Oh, I see, you meant to say "All the IP stack configuration stuff is in the registry"
Which broken configuration method that Windows offers you choose to employ when porting (and it was impressive for MS to come up with an even more broken system than .ini files) is pretty irrelevant to the heredity of the code you're porting.
Yabut - they claimed it was available across all of Manchester, when in fact it was only 50%.
Now, if it was 95%, I might have let that pass. But not 50%. No way. That's a blatant lie. False advertising. End of.

Err, so apart from the fact that the financials don't work, this is an excellent solution.

Yep, upload speed on this "top-of-the range" product remains at a staggeringly slow 12Mb. And my 60Mb service is still stuck at 3Mb upload. Years after we were promised an upgrade

Re: Not just broadband...
You had signed a contract, but BT breached it, rendering it void.
Re: Terrible Idea. But...
If what you're saying is true, then there must have been dramatic changes in BT Business Broadband support in the last 4 years. Which I don't believe.
I thought I'd got a result when someone promised me that he'd take personal responsibility for resolving an ongoing issue my client had. He gave me his name. I asked him what number I could contact him on, and he told me I could get him on the standard 0845 number.
So when the problem wasn't resolved, I called that number and asked for him. I was told he worked in another office (there were, apparently, three offices that calls to the number were distributed to). Could you transfer me, then, please ?? No, they couldn't. That was the final straw. To use the "I'll take personal responsibility for the issue" line as a tactic to get the caller off the line is despicable beyond belief. And for BT to be unable to transfer calls between offices when that's a service they sell...... (Yes, I know they can but just wouldn't)
On the basis of that as the lowest point of (many) low points I will never, ever, ever use BT as an end-user customer if there is an alternative. Ever again. Never. Is that clear ??
